LIMITED TWO-YEAR CONSUMER WARRANTY Directed Electronics, Inc. promises to the original purchaser, to replace this product should it prove to be defective in workmanship or material under normal use, for a period of two years from the date of purchase by the dealer as indicated by the date code marking of the product PROVIDED the product was installed by an authorized Directed dealer.
FEATURES Super-efficient Class D PWM design runs much cooler than conventional amps. High-speed MOSFET switching power supply. High-current complimentary Class D MOSFET outputs stable into one ohm loads. (D600 stable into two ohm load.) Switchable subsonic filter, 24dB/octave . Switchable 8 dB bass EQ function. Switchable 180° phase inversion. Remote subwoofer level control function. Variable input sensitivity optimizes match with different signal sources.
INSTALLATION GUIDELINES 1. Please read this owner’s manual carefully before installing this amplifier. 2. Disconnect the battery ground terminal prior to making any electrical connections. 3. Check for any hazards or obstructions such as gas tanks, fuel or brake lines, and wiring harnesses before mounting the amplifier. 4. Pick a mounting location that will provide adequate access and ventilation and protect the amplifier from heat, moisture, and dirt. 5.
tronics and the lower your speaker load, the more heat is generated. For low impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable. 9. Battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts); soldering the terminals after crimping is also recommended. 6 10.
FRONT PANEL CONNECTIONS/CONTROLS 1. RCA Input Jacks - Accepts line level outputs from head units or signal processors at voltages between 150mV and 7.5 volts. 7. Remote - Controls the subwoofer amplifier gain, from a remote location for ease of adjustment during listening. 2. RCA Line Output Jacks - These pass through RCA jacks can be used to send the input signal to a second amplifier.

REAR PANEL CONNECTIONS 1. Fuses - These fuses protect the amplifier against internal electrical damage and are meant to protect the amplifier only. All other power connections should be fused at the source. The D600 uses 1-40A fuse, the D800 uses 2-25A fuses, the D1200 uses 2-30A fuses, and the D2400 uses 3-30A fuses. 2. (+) 12 Volt Power - Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery.

SPEAKER WIRING DIAGRAMS Single subwoofer connection (top view) Two subwoofer connection (top view) NOTE: The dual + and -- sub-out terminals of the D600/D800/D1200/D2400 are paralleled internally and the combined load impedance should be taken into consideration when connecting multiple subwoofers.
COMBINING AMPLIFIERS The Directed D1200/D2400 subwoofer amplifiers have the capability of connecting two or more amplifiers of the same power rating together in a master/slave combination for increased power with accurate level matching. They are the Parallel Synced Gain and External Synced Bridged combinations. WARNING: DO NOT attempt to combine amplifiers of different power ratings. These amplifier combinations work correctly only if the Master and Slave amplifiers are identical models.
PARALLEL SYNCED GAIN CONNECTIONS/SETTINGS Refer to figure 5 for wiring details. 1. Input Signal - Connect these RCA jacks as described in the Front Panel Connection section of this guide. 2. Slave/Master Switch Set the slave/master switch on the master amplifier to the MASTER position. Set the slave/master switch on the slave amplifier to the SLAVE position.

EXTERNAL SYNCED BRIDGED CONNECTIONS/SETTINGS 1. Input Signal - Connect these RCA jacks as described in the Front Panel Connection section of this guide. 2. Slave/Master Switch Set the slave/master switch on the master amplifier to the MASTER position. Set the slave/master switch on the slave amplifier to the SLAVE position. Setting the slave/master switch on both amplifiers will automatically set the I/O RCA jack configuration according to each amplifiers slave or master designation.

MULTIPLE AMPLIFIER COMBINATIONS The Directed D1200/D2400 subwoofer amplifiers can also be used in multiples of the master/slave combinations allowing for unlimited expansion to a systems subwoofer section. To use multiples of amplifier combinations the following directions must be adhered to for best results. Amplifier configuration - Set up each master/slave amplifier combination as described for the combination type being used.
CROSSOVER SETTINGS AND GAIN ADJUSTMENT Your Directed Audio power amplifier needs to be adjusted carefully to achieve maximum performance. These are some guidelines to follow when fine-tuning the amplifier. 18 Because this amplifier is only designed for subwoofer applications, the low-pass crossover is active at all times. The crossover point is adjustable to allow more precise system operation.
LED TUBE INSTALLATION (OPTIONAL) This Directed Audio amplifier has been designed with a custom heat sink that can accommodate two (optional—not supplied) VARAD LED tubes. 1. Before installing the LED tubes, remove and discard the mounting feet from the VARAD LED tubes. 2. Slide each LED tube assembly into your Directed Audio amplifier heat sink. Ensure that the LEDs are facing out for optimal visibility. The wires from the LED tube assembly should be on the signal input end of the amplifier.
